| 1 | Spinal Cord Stimulation Frequency Influences the Hemodynamic Response in Patients with Disorders of Consciousness显示文摘Spinal cord stimulation(SCS) is a promising technique for treating disorders of consciousness(DOCs).However, differences in the spatio-temporal responsiveness of the brain under varied SCS parameters remain unclear. In this pilot study, functional near-infrared spectroscopy was used to measure the hemodynamic responses of 10 DOC patients to different SCS frequencies(5 Hz, 10 Hz, 50 Hz, 70 Hz, and 100 Hz). In the prefrontal cortex, a key area in consciousness circuits, we found significantly increased hemodynamic responses at 70 Hz and 100 Hz, and significantly different hemodynamic responses between 50 Hz and 70 Hz/100 Hz. In addition, the functional connectivity between prefrontal and occipital areas was significantly improved with SCS at 70 Hz. These results demonstrated that SCS modulates the hemodynamic responses and long-range connectivity in a frequency-specific manner(with 70 Hz apparently better), perhaps by improving the cerebral blood volume and information transmission through the reticular formation-thalamus-cortex pathway. | Juanning Si Yuanyuan Dang Yujin Zhang Yaxin Li Wenyue Zhang Yi Yang Yue Cui Xiaoping Lou Jianghong He Tianzi Jiang | 2018 | Neuroscience Bulletin2018，34，4： | 10 |
| 2 | 2.7 Ga Monzogranite on the Songnen Massif and Its Geological Implications显示文摘The formation and evolution of Songnen massif hasalways been a hot topic, and the presence of Precambrianbasement on the Songnen massif is still controversial: (1)Lacking of Pre-Paleozoic dating results, the Precambrianbasement on Songnen massif does not extend largelyaccording to the isotopic dating results of core frombasement, (2) the existence of gneiss from deep drill holesof the Songliao Basin makes some researchers considerthat Precambrian basement should exist on the Songnenmassif and another proof is that the geophysical featuresof gravity. | WU Xinwei ZHANG Chao ZHANG Yujin GUO Wei ZHANG Chao CUI Tianri YANG Yajun HU Jianfei SONG Wanbing | 2018 | Acta Geologica Sinica(English Edition)2018，92，3： | 8 |
| 3 | Brain Network Studies in Chronic Disorders of Consciousness:Advances and Perspectives显示文摘Neuroimaging has opened new opportunities to study the neural correlates of consciousness, and provided additional information concerning diagnosis, prognosis, and therapeutic interventions in patients with disorders of consciousness. Here, we aim to review neuroimaging studies in chronic disorders of consciousness from the viewpoint of the brain network, focusing on positron emission tomography, functional MRI, functional near-infrared spectroscopy,electrophysiology, and diffusion MRI. To accelerate basic research on disorders of consciousness and provide a panoramic view of unconsciousness, we propose that it is urgent to integrate different techniques at various spatiotemporal scales, and to merge fragmented findings into a uniform‘‘Brainnetome''(Brain-net-ome) research framework. | Ming Song Yujin Zhang Yue Cui Yi Yang Tianzi Jiang | 2018 | Neuroscience Bulletin2018，34，4： | 8 |
| 4 | Changes of auditory evoked magnetic fields in patients after acute cerebral infarction using magnetoencephalography显示文摘Auditory evoked magnetic fields were recorded from 15 patients with acute cerebral infarction and 11 healthy volunteers using magnetoencephalography.The auditory stimuli of 2 kHz pure tone were binaurally presented with an interstimulus interval of 1 second.The intensity of stimuli was 90 dB and the stimulus duration was 8 ms.The results showed that the M100 was the prominent response, peaking approximately 100 ms after stimulus onset in all subjects.It originated from the area close to Heschl's gyrus.In the patient group,the peak latency of M100 responses was significantly prolonged,and the mean strength of equivalent current dipole was significantly smaller in the affected hemisphere.The three-dimensional inter-hemispheric difference of the M100 positions was increased in the patient group.Our experimental findings suggested that impairment of cerebral function in patients with acute ischemic stroke can be detected using magnetoencephalography with the higher spatial resolution and temporal resolution.Magnetoencephalography could provide objective and sensitive indices to estimate auditory cortex function in patients with acute cerebral infarction. | Zhanyong Sun Chunfeng Song Jilin Sun Ling Li Yanhong Dong Jianhua Wang Jie Wu Wenzhu Cui Yujin Wu Peiyuan Lv | 2012 | Neural Regeneration Research2012，7，24： | 1 |

| 6 | 广东省放疗医师对乳腺癌改良根治术后放射治疗认识现状调查分析(英文)显示文摘Objective:The aim of our study was to comprehensively access current status of radiotherapy physicians' opinions in post-mastectomy radiotherapy(PMRT) for breast cancer in Guangdong province.Methods:From June 2007 to June 2008,questionnaires on the clinical value,sequencing with chemotherapy and endocrine therapy,indications and irradiated targets for PMRT were sent to physicians of all radiotherapy departments registering at Radiotherapy Professional Committee of Guangdong Anti-cancer Association.Results:There were 126 physicians joining this investigation.Proportions of physicians who accepted the views that PMRT could merely improve local control or can improve both local control and overall survival were 100% and 25.2%.The most common sequences of PMRT and chemotherapy or endocrine therapy were 'sandwich' and sequential modes,performed 46.9% and 59.5% respectively.The median interval of surgery and PMRT was 8 weeks.Proportions of physicians who accepted T3-4 diseases,or four or more axillary lymph nodes metastasis,or T1-2 with 1-3 positive lymph nodes,or T1-2N0 with primary tumor located in the center or inner quadrant as the indications of PMRT were 97.6%,100%,46.8%,13.5%,respectively.Proportions of physicians who accepted chest wall,supraclavicular region,internal mammary chain or axilla as irradiated targets were 86.5%,100%,49.2% and 38.9% respectively.Conclusion:For Radiotherapy physicians of Guangdong Province,there is still lacking of consensus in the opinions of whether PMRT can improve survival,and optimal sequencing with chemotherapy or endocrine therapy,and how to make decision for patients with T1-2 with 1-3 positive lymph nodes,and rational irradiated targets,which requires advanced professional training for physicians and further prospective clinical trial evidences to guide clinical practice. | Xiaobo Huang Ge Wen Nianji Cui Yujin Zhang Taixiang Lu Xunxing Guan Mengzhong Liu | 2011 | The Chinese-German Journal of Clinical Oncology2011，10，4： | 0 |
| 7 | Influencing factors and prevention measures of casing deformation in deep shale gas wells in Luzhou block,southern Sichuan Basin,SW China显示文摘Based on structural distribution and fault characteristics of the Luzhou block,southern Sichuan Basin,as well as microseismic,well logging and in-situ stress data,the casing deformation behaviors of deep shale gas wells are summarized,and the casing deformation mechanism and influencing factors are identified.Then,the risk assessment chart of casing deformation is plotted,and the measures for preventing and controlling casing deformation are proposed.Fracturing-activated fault slip is a main factor causing the casing deformation in deep shale gas wells in the Luzhou block.In the working area,the approximate fracture angle is primarily 10°-50°,accounting for 65.34%,and the critical pore pressure increment for fault-activation is 6.05-9.71 MPa.The casing deformation caused by geological factors can be prevented/controlled by avoiding the faults at risk and deploying wells in areas with low value of stress factor.The casing deformation caused by engineering factors can be prevented/controlled by:(1)keeping wells avoid faults with risks of activation and slippage,or deploying wells in areas far from the faulting center if such avoidance is impossible;(2)optimizing the wellbore parameters,for example,adjusting the wellbore orientation to reduce the shear force on casing to a certain extent and thus mitigate the casing deformation;(3)optimizing the casing program to ensure that the curvature radius of the curved section of horizontal well is greater than 200 m while the drilling rate of high-quality reservoirs is not impaired;(4)optimizing the fracturing parameters,for example,increasing the evasive distance,lowering the single-operation pressure,and increasing the stage length,which can help effectively reduce the risk of casing deformation. | HAN Lingling LI Xizhe LIU Zhaoyi DUAN Guifu WAN Yujin GUO Xiaolong GUO Wei CUI Yue | 2023 | Petroleum Exploration and Development2023，50，4： | 0 |
